  • Apparatus and methods for handling materials in a 3-D printer
    Patent number: 7828022
    Abstract: The present invention is directed towards methods and apparatus for handling powder in a 3D printer. The invention includes a means of transporting powder from multiple sources to a powder dispensing apparatus with minimal user intervention, thus reducing contamination of the 3D printer and surrounding area with loose powder, while also providing a means of improving the recycling of powder for re-use.

  • Method and system to optimize capacity of a CDMA cellular communication system
    Patent number: 6128500
    Abstract: A method and system for optimizing system capacity and allocation in a CDMA cellular communication system obtains a current call volume and associated call characteristics for each of a plurality of cell sites in the system, and estimates effective boundaries for each of the plurality of cell sites to minimize the weighted sum of powers received at selected base stations. Selection of base stations can include highly loaded sites and adjoining cell sites. System parameters are then controlled to effect the estimated cell site boundaries. Thus, the present invention allows for dynamic shrinking and enlarging of cell boundaries to enhance the system capacity advantages of CDMA while maintaining contiguous coverage and avoiding coverage holes.

  • Method and system for determining optimized SONET rings
    Patent number: 6094417
    Abstract: A SONET planning tool is provided for generating optimized SONET rings based on an existing SONET system capacity and anticipated system demand at minimal cost. The planning tool includes an analytical process that accurately models and utilizes embedded systems, linear chains, unidirectional rings, and bi-directional rings based on existing capabilities. In addition, large forecasted demands can be preprocessed with dedicated two-node rings, and multi-period studies can be generated.
